RETORT.

SPECIFICATION forming part of Letters Patent No. 782,207, dated Feb uary '7, 1905.

Application filed September 27,1904. Serial No, 226,189.

To (LU 1071 0112 it 71m concern:

Be it known that I, JOHN L. Jncnsox, a citi- Zen of the United States, residing at Saginaw, in the county of Saginaw and State of Michigan, have invented certain new and useful Improvements in Retorts, of which the following is a specification, reference being bad therein to the accompanying drawings.

The invention relates generally to retorts especially designed in use for the hardening of bricks by steam; and it consists in means for protecting the bricks from injury from the condensation of the steam, as will be hereinafter set forth.

In practice brick-retorts are composed of overlapping sections of metal riveted at their edges. These rivets being rapid conductors of heat maintain a lower temperature than that of the steam within the retort, causing condensation on the surface of the rivet-heads. The bricks to be hardened are brought in the retort on a car and during the baking process are sufficiently soft to be injured by the drip from overhead rivets, it being not at all unusual to have a large number of bricks ruined in this manner in each hardening.

The essential object of this invention is to obviate by simple means the injury to the bricks described, as will be presentlyset forth.

In the drawings, Figure 1 is a vertical central section through a retort, illustrating the means employed for protecting the bricks. Fig. 2 is an enlarged sectional view of a portion of the shell of the retort, illustrating the application of the protecting means; and Fig 3 is a detail sectional view taken on line 1: ,r 5

of Fig. 2.

A represents the shell of a retort of any suitable type adapted to harden bricks through the agency of steam, B the track laid on the bottom of the retort, as indicated, and C the car traveling on the track.

1) represents a load of bricks on the car, and E is a suitable receptacle in which the lime is prepared.

The shell of the retort is composed of a number of sections preferably overlapping and connected by suitable fastening devices, such as rivets F.

G represents the protecting device referred to adapted to convey the drip from the rivethcads, due to the condensation of the steam, and prevent injury to the bricks beneath the rivets. In construction the protecting device is in the form of a trough, preferably U-shaped in cross-section and curved longitudinally, so as to conform to the internal configuration of the arch or overhead portion of the retort. One or more troughs are used, according to the number of sections of which the rctort is composed and the series of fastening devices therefor. Each trough is preferablyattached to the retort-shell by suitable bolts H, which pass through the bottom of the trough and through the shell A, the bolts having flat heads engaging the troughs, so that they will set flush with the convex side of thelatter. Preferably the bolts are secured to the shell by jam-nuts; but any other way of securing the same may be employed, as may be desired. The ends of each trough are carried down to a point in the vertical walls of the shell a suitable distance to collectall moisture that may fall from the overhead rivets and that may possibly drop upon the bricks in the car. Any suitable means may be employed in connection with the trough to convey therefrom the condensation, or, if desired, the ends of each trough may be left open and the condensation allowed to drop therefrom on the retort-bottom.

\Vhat I claim as my invention is 1. In combination with an arched retort composed of sections and suitable fastening devices for the sections projecting within the retort beyond its inner surface, of a drip-conveyer within said retort, comprising a trough curved longitudinally to conform to the internal configuration of the arch, said trough being attached to said retort by bolts passing therethrough, and having their heads flush with the convex side of said trough.

2. In combination with an arched retort, composed of sections and suitable fastening riveted together, of a trough-shaped conductor therein arranged beneath each circumferential series of rivets in proximity to the retort-top, the ends of the trough being open and extending downwardly to convey the condensation to the sides of the retort, substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.
